BENJAMIN EDWARD MEACHAM, OF LORAIN, OHIO, ASSIGNOR TO AMERICAN STOVECOMPANY, OF ST; LOUIS, MISSOURI, A CORPORATION OF NEW JERSEY.

BURNER FOR WATER-HEATERS.

To all whom it may concern:

Be 't known that I, BENJAMIN E. MEACHAM, a citizen of the United States,residing at Lorain, in the county of Lorain and State of Ohio, haveinvented certain new and useful Improvements in Burners forWater-Heaters, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to improvements in burners for water heaters.

The object of my invention is to provide an improved burner in which themixing cone is well protected from condensation and overheating, and atthe same time pro vide a burner in which there will be no back fire. I

Another object of my invention is to provide a burner of this. characterwhich is easy to assemble and repair and which has no packed or cementedjoints, and at the same time produce a cheap and efiective burner whichwill properly distribute the heat and cause perfect combustion.

A still further object of my invention is to provide a simple, cheap andeffective burner of this character having certain details of structureand combination of parts hereinafter more fully set forth.

Referring now to the accompanying drawings; Figure 1 is a perspectiveview of my improved burner. Fig. 2 1s a transverse vertical sectionalview taken on the line 22, Fig.1. Fig. 3 is a-longitudinal verticalsectional view taken at right angles to Fig. 2, taken on the line 33,Fig. 2. Fig. 4 is an enlarged perspective view of a gas supply tube andthe burner supporting base. Fig. 5 is a. perspective view of a shutterfor regulating the air to the gas supply tube.

Referring now to the drawings, 1 represents the gas and air supply tubeof my improved burner which is of an elongated form and has at its lowerend the enlarged outwardly flared air-bell 2, all of which is of theusual construction of burners of this character. The lower end of theair-bell is provided with a beading 3, and opposite Speeification ofLetters Patent; Patented June 15 a 1915, Application filed January 21,1915. Serial No. 3,553.

sitely arranged air-inlet openings 7 by means of which air is suppliedto the tube.

Surrounding the cylindrical neck 5 is a cylindrical collar 8, which isprovided at its upper end with an outwardly extending annular shutter 9,provided with openings 10 adapted to register with the openings 7. Thisshutter 9 rests flat against the closure 4 of the air-bell and isrotatably mounted on the neck.

The lower side of the shutter 9 is provided with a rib 11, provided atits outer end with the upwardly extending lug 12, which extends upwardlybeyond the beadmg 3, and has passing therethrough a set screw 18, whichis adapted to engage the outer face of the flared air-bell 2, beyond thebeading 3, and thus the shutter is free to revolve upon the neck 5, butlocked against downward movement thereon. By this construction it willbe seen that the shutter may be rotated or oscillated so as to bring theopenings 10 to register with the openings 7 so that the amount of airpassing to the tube 1 is'readily regulated. The set screw 13 istightened when the shutter has been adjusted to its proper position andthus the proper amount of air is supplied to the tube.

the flange 20 formed therearound and which fits a perforated copper cone21, which. forms a mixing chamber for breaking up the particles of gasand causing them to thoroughly mix with the air whereby the burner atthe point of combustion is supplied with'a properly mixed gas.

The burner head consists of a rectangular body portion 22, which has atits lower end on opposite sides the outwardly flared walls 23 and 24,which form a. central dome adapted to correspond with the base 14, andis adapted to rest upon the base on the outside of the flange 20 andform a tight joint therewith. The walls and 24 form a domed chamber andat its upper end is a support 25, which is adapted to engage the upperend of the cone and hold it in the depressed portion 19 of the base.'Communicating with the domed chamber on opposite sides are openings 26and 27 which communicate with the rectangular burner head 22, andwhereby the gas after it has become thoroughly mixed with the air afterpassing through the cone 21, passes to the rectangular burner'22. Thedome-shaped chamber formed by the walls 23 and 24 is provided withoutwardly extending ears 28 and 29 which are arranged directly above theears 15 and 16 and are provided with openings 30 and 31 through whichthe bolts 32 and 33 pass.

By this structure it will be seen that the mixing chamber is clampedtightly down upon the circular base 14 and the support engaging thecone, 21 holds the cone in the depressed portion 19against.displacement. The upper end of the rectangular burner head 22 is open asindicated at 3 1 and in which closely fits the distributer head 35.

This head is held in the open top of they burner head 22 by means of apin .36. The

distributer is preferably formed with a V- shaped groove at the top andhas on opposite sides the obliquely arranged curved grooves 37 and 38arranged on opposite sides which form passages to allow the escape ofgas from the burner head. The gas 'is burned at the outlets of thegrooves 37 and 38.

By this construction and arrangement of parts as herein shown, it willbe seen that applicant has produced a burner in which the parts arereadily assembled or disassembled, and in which a tight joint is made toprevent the leakage of gas therefrom, and by the arrangement of thecopper coneshaped mixing chamber 21, it will be seen that the air andgas is thoroughly .broken up and mixed as it passes therefrom and entersthe rectangular burner head 22 in a combustible gas. It thence passesfrom the rectangular burner head 22 out through the grooves orpassages37 and 38 and is burned.

Having thus described my invention what I claim and desire to secure byLetters Patent is:

1. A burner of the character described, comprising a burner head havingan open upper end, a distributor head removably secured in the openupper end of the burner head, the lower end of the burner head having adome-shaped portion, a base having a circular portion closing the lowerend 4 of the dome-shaped portion of the burner head and having acombined air and gas supply tube, a perforated cone carried by thecircular base portion and extending within the dome-shaped portion ofthe burner head, and means for fastening the 2 base and burner headtogether.
